I have a few friends who are new to homeschooling. Some are using tried and trusted curriculum; some are trying a couple of different ones to see what works well for their children. The bottom line with choosing a curriculum for your child is that it is okay to change if something isn't working. Kids don't fit into cookie-cutter learning styles. What works for some of my children, doesn't work for others. And it's okay to try and find that one style that will engage your child and open new worlds of learning, knowledge and understanding for them.
You're doing a great job, momma!!
